Text linked to audio?

Hi there,
I’m really new to blender, I actually just started using it today. I’m usually pretty good at using software like this but I underestimated the difficulty of the tutorial I was trying to follow.

Anyways, I hit a problem towards the end of the tutorial and I think it was something to do with rooting light rays to the audio, and I think I linked my text to the audio instead of the light rays I made or something like that because my text seems to be locked and i cant add other keyframes on to it.

Basically what is happening is that the keyframes i made on the text disappeared and now instead of moving with the keyframes my text spazzes/pulses randomly with the bass of the music.

Here’s a screenshot:

Thanks to whoever might read this and help me out
